The first head coach of the Georgia Gwinnett College softball program, Kat Ihlenburg has developed the Grizzlies into a championship squad built upon toughness, character and a devotion to its community.

The 2015 GGC squad posted a 37-16 record under Ihlenburg and was marked by a dominating performance at home at the Grizzly Softball Complex. The Grizzlies went 26-2 in Lawrenceville on the season, winning their first 22 consecutive home games to start the year. Senior infielder Cassidy Littlefield cemented herself as one of the top players in the country, earning her second straight NAIA first team All-American nod and being named unanimous A.I.I. Player of the Year.

The 2014 season, GGC’s first as a fully-eligible NAIA member, saw Ihlenburg lay a championship foundation for her program by guiding Georgia Gwinnett to an outstanding 39-10-1 record. The Grizzlies earned votes for the first time in the Top 25 Coaches’ Poll, claimed their first postseason victory, and boasted four all-conference selections, including A.I.I. Co-Player of the Year Cassidy Littlefield.
